"The following packages have unmet dependencies:
lib32gomp1 : Depends: gcc-4.8-base (= 4.8.2-19ubuntu1) but 4.8.4-2ubuntu1~14.04 is to be installed
libgl1-mesa-glx:i386 : Depends: libglapi-mesa:i386 (= 10.1.3-0ubuntu0.3)
E: Unable to correct problems, you have held broken packages."

I am at a loss as to what to do next, I can find this info in my package manager but do not see any other option to install any other versions.

OK, I got it:
Did clean install of Mint 17.3 after spending a weekend mucking around with Windows 10 (Not related to Medusa).

The first attempt I installed csh, this attempt I used tcsh, then I used the above command to install the dependencies, I then ran the installer and it completed without any issues.

Launch would still crash to desktop, I used the terminal to cd to the appropriate folder and tried to launch from the terminal using ./startmedusa which opened the terminal but did not launch, but it at least displayed the missing dependency.
